Manufacturing method of nanometer titania formaldehyde-reduced bamboo plywood

Abstract

A manufacturing method of nanometer titania formaldehyde-reduced bamboo plywood includes the following steps of (1) sulfonation treatment of nanometer titania, (2) cold plasma treatment of bamboo veneers, (3) preparation of the bamboo veneers with the surfaces loaded with the nanometer titania, and (4) preparation of the nanometer titania formaldehyde-reduced bamboo plywood, specifically, the prepared bamboo veneers with the surfaces loaded with the nanometer titania are cut into a certain size according to requirements, single-face gluing is conducted by adopting urea resin or melamine urea-formaldehyde resin, longitudinal and transverse crossing laying is conducted according to the laying requirements of common plywood, the veneers are displayed for 10-30 min after laying, and then the veneers are subjected to hot pressing by being placed in a hot pressing machine, so that the nanometer titania formaldehyde-reduced bamboo plywood is obtained. According to the manufacturing method ofthe nanometer titania formaldehyde-reduced bamboo plywood, the titania is distributed evenly, operation is simple, the loading quantity is large, and the titania is firmly combined with wood and bamboo materials.

Description

technical field [0001] It belongs to the field of composite material preparation technology, and the patent classification number is B01J. The invention loads nano-titanium dioxide material on the surface of the bamboo veneer, thereby preparing the bamboo plywood, which has the function of photocatalytically degrading formaldehyde, and can be used in the production and manufacture of furniture boards. Background technique [0002] Wood is recognized as a green material in the world. Because of its pleasing color, elegant and beautiful texture, good touch, high strength-to-weight ratio and easy processing, wood has been the material of choice for human furniture production and interior decoration since ancient times. Among the four major materials in the world today - wood, plastic, steel, and cement, it is the only resource that is both renewable and recyclable. It can be said that whether it is now or in the future, wood is always an ideal consumption choice for people. I...
